Please recommend a place where I can buy candies, chocolates and other items for candy buffet aside from Divisoria.

You can try Joshua Gummies on Facebook. I inquired from them when we were planning for my cousin's baby shower but sadly, it didn't push through. They respond fast and they have wide options to choose from. They have competitive rates, too, because they're a supplier. It's truly a one-stop shop for your dessert buffet needs.
